When I started learning Python, I knew I wanted to do more than memorize syntax. I wanted to build projects that would challenge me to think, solve problems, and understand how different parts of a program work together.
After working on projects like a Library Management System, I decided to take on another challenge: building a text-based RPG Battle System using Python and Object-Oriented Programming (OOP).
It has been a great learning experience so far.
What I wanted to build
The goal was to create a simple battle system where different characters could fight each other, each with their own abilities and limitations.
I created three character types:
- Warrior: Can perform a powerful attack that deals double their normal attack power.
- Mage: Can cast a powerful spell that deals double damage but consumes mana.
- Archer: Can perform a ranged attack that deals 1.5 times their attack power but consumes an arrow.
Each character also has health, attack power, and defense.
Applying Object-Oriented Programming
One of the most important parts of this project was learning how to use inheritance.
I created a base Character class to hold the common properties and behaviors shared by all characters.
Instead of writing the same code repeatedly for the Warrior, Mage, and Archer, I used inheritance to allow each specialized class to reuse the functionality of the parent class.
For example, the subclasses could inherit the normal attack behavior while implementing their own special abilities.
This helped me understand why inheritance is useful and how it can make code more organized.
Adding special attacks
I wanted each character to have a unique fighting style.
The Warrior has a 10% chance of performing a power attack, the Mage has a 20% chance of casting a spell when they have enough mana, and the Archer has a 30% chance of performing a ranged attack when they have arrows available.
I used Python's random module to introduce these chances.
This taught me that implementing a feature is only part of the job. I also needed to make sure the conditions were correct and that each ability behaved as expected.
Managing resources
Another important lesson was resource management.
The Mage needs at least 10 mana to cast a spell, and each successful spell consumes 10 mana. The Archer needs at least one arrow to perform a ranged attack, and each successful ranged attack consumes one arrow.
I also learned the importance of testing edge cases.
For example, what should happen if the Mage has only 5 mana? Should the spell still work?
I tested this situation and confirmed that the spell returns zero damage, Gandalf keeps his remaining mana, and the opponent takes no damage.
These small tests helped me understand how to protect a program from invalid actions.
Creating the battle system
I then created a Battle class to manage the fight between two characters.
The battle continues while both characters are alive. Each character attacks in turn, their opponent's health decreases, and the battle ends when one character is defeated.
I also improved the battle messages so that special attacks are announced clearly.
Seeing a message such as:
Aragorn unleashes a POWER ATTACK!
makes the battle easier to follow and helps me verify that the correct ability was triggered.
Challenges and lessons learned
This project has reminded me that understanding a concept and applying it independently are two different things.
Sometimes I understand what a method should do but struggle to organize the logic or remember the exact syntax. Instead of giving up, I break the problem into smaller pieces, test each method, and investigate unexpected results.
I've learned to pay attention to:
- Inheritance and method overriding.
- Calling parent methods with
super(). - Conditional logic and random numbers.
- Managing health, mana, and arrows.
- Returning values from methods.
- Testing edge cases and checking output.
- Using clear messages to understand what my program is doing.
I'm still working through the project, but each step is helping me become more comfortable with Python and OOP.
The biggest lesson so far is that building a project isn't just about getting the code to run. It's about understanding why it works, identifying what can go wrong, and learning how to fix it.
I'm continuing my Python journey, one project at a time.
Have you built a game or another project that helped you understand OOP better? I'd love to hear what you learned from it!
